AUGUSTE CLAUDE ADOLPI-IE BOUCI-IABD, OF NICE, FRANCE.

DEVICE FOR AUTOMATICALLY CONTROLLING LIGHTING GAs CONDUITS,

' CIRCUITS, AND THE LIKE.

Application filed March 30, 1914.

To all whom it may concern:

Be itknown that I, AUGUs'rn CLAUDE AooLH-in Booormno, a citizen'of the French Republic, and resident of Nice, France, have invented a certain new and useful Device for Automatically Controlling Lighting- Gras Conduits, Electric Circuits, and the like, of which the following is a specification.

This invention relates to a device for controlling the opening and closing of conduits adapted to convey lighting gas, and more particularly to that class of such devices adapted to be used in connection with some means for lighting the inflammable fluid conveyed through saidconduits, and has for its primary object the provision of such a device which shall be adapted to automatically open and close such conduits at a desired time of the day.

A still further object of the invention is the provision of a device of the character described with a valve for opening and closing said conduit, the said valve being operated by means of suitable mechanism controlled by other suitable timing mechanism, which 1s in turn operated in accordance with a predetermined set relative to the time of day the conduit is to be opened or closed.

With the foregoing and other objects in view, as will hereinafter appear, this invention consists inv the peculiar combination and arrangement of Various correlated elements of a device for automatically con-- trolling lighting gas conduits, as set forth in the following specification and more particularly brought out in the appended claims.

Referring to the accompanying drawings forming a portion of this application and in which the same referencecharacters indicate the same parts wherever used:

Figure 1 is a vertical section through the device.

Fig. 2 is a front view of the same.

Fig. 3 is a section on line AA of Fig. 1.

Fig.4 is a view showing certain details.

The device comprises a casing 1, adapted to house a suitable clock-work 2, carrying a spindle 3, on which is mounted an indicating finger ,4, secured thereto by means of a clasp 5, to permit of adjustment of the finger 4 upon the spindle 3. The finger 1 is adapted to move in front of a single dial 6,

providedwith twenty-four divisions corresponding with the twenty-four hours of the day. The dial 6 is mounted in the casing 1, and is provided at its periphery with two slots 7 and 8, through which extend two indexes 9 and 10, frictionally mounted upon a sleeve carried by the spindle 3, the indexes 9 and 10 projecting over the divisions of the dial 6, without interfering with the finger 1, in orderito permit of the indexes 9 and 10 being shifted between and around the dial 6 within the slots 7 and 8. The index 9 18 provided with a shoulder 11, and the index 10 is provided with a shoulder 12, the said shoulders being disposed in different vertical planes. Carried by the spindle and adjacent the shoulders 11 and 12 is a pivot 13, carrying a cam head 14, which is adapted upon rotation of the shaft 3, to alternately. strike the shoulders '11 and 12, so that the member 13 alternately oscillates toward the left and the right, carrying with it the two levers 15, which by means of rods 16, extending through a central aperture of a partition 17 of the casingl, oscillate the disk 18, which engages the lower prongs of a forked member 19, slidably mounted upon a spindle 20. The .upper prongs of said fork 19 extend on either face of a gear wheel 21, which carries diametrically opposite pins 22. Wheel 21 is keyed upon a shaft 23, which is parallel with respect to shaft 3, and operated by means of the barrel 2 1 of the clock work 2, through the'medium of a gear 24, engaging the gear 25. A regulating blade wheel 26 serves to govern the motion of wheel 21, through the medium of the gear 26, a shaft 26" and a second gear 26 engaging the wheel 24, as shown in Fig. 1, thus causing the rotation of the wheel 26, which by contact with the air, governs the speed of the wheel 21. Upon the forked member 19 is provided a hooked bar 27, normally projecting into the path of said blade wheel 26, preventing rotation thereof. for a purpose to be herein after explained.

The shaft 23 extends beyond the rear wall of the casing 1, and is provided with a square central member 28, which engages a correspondingly shaped end of a spindle 29. 30 designates a gas inflow chamber of any suitable construction, having an outer wall 30 which carries the outer end'of the spindle 29. The spindle 29 is provided with arevolution.

a cam member 31, carrying a member 32, provided with two oppositely disposed valve cones 33, adapted to control the inlet and outlet ducts of the gas chamber 30, designated by the numerals l0 and 4:1 respectively.

In order to prevent the escape of gas from the chamber 30, through the aperture required for the spindle 29, the spindle 29 18 provided with a plurality of circular grooves 39, and a double cam packing mounted in a stuiiing box 35, in the inner wall of the chain er 30.

The operation of the device is as follows:

Should it be desired to light the burners controlled by the device at six oclock P. M. and to extinguish the same at five oclockP. hi, the index 9 isshifted by hand on division 18 of the dial, and index 16 on division 5, corresponding with the hours of the twentyfour hours of the day, the finger which corresponds with the position of the member 13 reaches division 18 upon dial 6, the cam ll meets the shoulder 11 and causes the member 13 to swing, carrying with it by means of the levers 15 arms 16, and the disk 18 shifts the double fork 19 laterally along its spindle 20. The member .19 is now thrown out of engagement with the wheel 21 and the pins 22. Due to the lateral shifting of the member 19 upon shaft 20 and the subsequent rotation of the arms 19 and 27 under the action of thespring 38, the hooked bar 97 is disengaged from the blade wheel 26, so that the parts 26, 21 and 23, including the means necessary to operate the blade wheel 26 move again under the action of gears 2i and 2 5, causing the rotation of shaft 23, which in turn causes a rotation of the spindle 29 and the eccentric 31 to cause movement of theframe-work 32, to operate the desired valve cone 33 to open said outlet and light the lmrners, the said gas outlet duct being fully opened after the'shaft 3 has performed half WV hen. the shaft 23 is rotated through an arc of one hundred and eighty degrees, the second pin of wheel 21 strikes the second upper prong of the double forli 19, which has been previously laterally shifted in the path of said pin. When the said second pin 2:2 strikes the prong the fork 1'9 pivots to its shaft 20 and pushes the hooked bar 2? into the path of the blade wheel 26 stopping the rotation thereof and the elements connected therewith, leaving the outlet'valve' open. When the lighting period has elapsed, the member 13 will strike the shoulder 12, and by means of the cam 1-1, repeat the operation above described, the hooked bar 27 being disengaged from the blade wheel 26, by means of a spring 38, which normally tends to pull said member out of engagement with the blade wheel, whereupon the shaft 23 is again rotated to shift the valves 33 to close the gas ports and prevent flow therefrom through the burners, a further rotation of the device being stopped in the manner described for the first or opening operation. 1
